stack setup won't recognize changes in .cabal file - haskell

Question

I've added "QuickCheck" to the "build depends" section of the .cabal file but when I do stack setup the "QuickCheck" section of the file gets removed and I get this error:
It is a member of the hidden package ‘Cabal-3.2.1.0’.
You can run ‘:set -package Cabal’ to expose it.
(Note: this unloads all the modules in the current scope.)
Use -v (or `:set -v` in ghci) to see a list of the files searched for.

1 | import Distribution.Simple

the stack build and stack ghci work fine but stack test gives this error:
Could not find module ‘Test.QuickCheck’
Use -v (or `:set -v` in ghci) to see a list of the files searched for.

3 | import Test.QuickCheck
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Answer 1

Your cabal file was generated from the package.yaml file in that directory:
-- This file has been generated from package.yaml by hpack version 0.34.6.

If you want to add new dependencies, add them to package.yaml. Any changes you make to the .cabal file will get overridden.
